Objective: To examine the feasibility and surgical approach of removing type D trigeminal schwannoma through nasal cavity and nasal sinus under endoscope. Methods: Eleven patients with trigeminal schwannoma who were treated in the Department of Otorhinolaryngology, Qilu Hospital of Shandong University from December 2014 to August 2021 were analyzed retrospectively in this study. There were 7 males and 4 females, aged (47.5±13.5) years (range: 12 to 64 years). The neoplasm involved the pterygopalatine fossa, infratemporal fossa, ethmoidal sinus, sphenoid sinus, cavernous sinus, and middle cranial fossa. The size of tumors were between 1.6 cm×2.0 cm×2.0 cm and 5.7 cm×6.0 cm×6.0 cm. Under general anesthesia, the tumors were resected through the transpterygoid approach in 4 cases, through the prelacrimal recess approach in 4 cases, through the extended prelacrimal recess approach in 2 cases, and through the endoscopic medial maxillectomy approach in 1 case. The nasal endoscopy and imaging examination were conducted to detect whether neoplasm recurred or not, and the main clinical symptoms during follow-up. Results: All the surgical procedures were performed under endonasal endoscope, including Gross total resection in 10 patients. The tumor of a 12-year-old patient was not resected completely due to huge tumor size and limited operation space. One patient was accompanied by two other schwannomas located in the occipital region and the ipsilateral parotid gland region originating from the zygomatic branch of the facial nerve, both of which were removed concurrently. After tumor resection, the dura mater of middle cranial fossa was directly exposed in the nasal sinus in 2 cases, including 1 case accompanied by cerebrospinal fluid leakage which was reconstructed by a free mucosal flap obtained from the middle turbinate, the other case was packed by the autologous fat to protect the dura mater. The operation time was (M(IQR)) 180 (160) minutes (range: 120 to 485 minutes). No complications and deaths were observed. No recurrence was observed in the 10 patients with total tumor resection during a 58 (68) months' (range: 10 to 90 months) follow-up. No obvious change was observed in the facial appearance of all patients during the follow-up. Conclusion: Type D trigeminal schwannoma involving pterygopalatine fossa and infratemporal fossa can be removed safely through purely endoscopic endonasal approach by selecting the appropriate approach according to the size and involvement of the tumor.

Long non-coding RNAs (lncRNAs) play a significant role in maintaining tissue morphology and functions, and their precise regulatory effectiveness is closely related to expression patterns. However, the spatial expression patterns of lncRNAs in humans are poorly characterized. Here, we constructed five comprehensive transcriptomic atlases of human lncRNAs covering thousands of major tissue samples in normal and disease states. The lncRNA transcriptomes exhibited high consistency within the same tissues across resources, and even higher complexity in specialized tissues. Tissue-elevated (TE) lncRNAs were identified in each resource and robust TE lncRNAs were refined by integrative analysis. We detected 1 to 4684 robust TE lncRNAs across tissues; the highest number was in testis tissue, followed by brain tissue. Functional analyses of TE lncRNAs indicated important roles in corresponding tissue-related pathways. Moreover, we found that the expression features of robust TE lncRNAs made them be effective biomarkers to distinguish tissues; TE lncRNAs also tended to be associated with cancer, and exhibited differential expression or were correlated with patient survival. In summary, spatial classification of lncRNAs is the starting point for elucidating the function of lncRNAs in both maintenance of tissue morphology and progress of tissue-constricted diseases.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Abstract: Objective　To construct SARS-CoV-2 receptor binding domain molecular probe for monoclonal memory B cell sorting and obtain RBD specific neutralizing antibodies from peripheral blood mononuclear cells (PBMCs) of COVID-19 convalescents by single-cell sorting. Methods　The SARS-CoV-2 RBD sequence was downloaded from GenBank, and the Avi tag and 6-histidine tags were added at the C-terminal. After codon optimization, it was chemically synthesized, cloned into the pDRVI1.0 vector, expressed after transfection of 293F cells, and biotinylated consequently. RBD-specific B cells were sorted out with this probe1 from the PBMCs of convalescents recovered from COVID-19. After B cells were lysed, the variable regions of heavy chain and light chain were amplified, cloned into the antibody expression vector, and transfected into 293F cells to express the antibody. Then the antibody was purified from the supernatant using protein A column and SARS-CoV-2 pseudovirus was used to test their neutralizing activity. Results　RBD-Avi probe was produced and successfully biotinylated sequentially with an efficiency of 30%-50%. Western blot analysis revealed that the biotinylated probe was recognized by the antibodies purified from COVID-19 convalescent plasma. Using this probe, 7 and 16 RBD-specific memory B cells were successfully isolated from the PBMCs of two convalescent individuals, accounting for 0.24% and 0.17% of the total cell population, respectively. After amplifying the variable regions of antibody heavy and light chains from the lysed B cells, 7 and 12 pairs of antibody heavy-light chains were obtained. A total of 16 antibodies were expressed in the convalescent individuals, and most of the purified antibodies showed neutralizing activity against the pseudovirus, with IC50 values of 6 antibodies below 1 μg/mL. The IC50 values of XJ-A9 and SCF-F1 against the wild-type pseudovirus were 0.07 μg/mL and 0.35 μg/mL, respectively. Conclusion　The SARS-CoV-2 RBD molecular probe constructed in this study has good antigenicity, and the isolated antibodies present neutralizing activity against wild-type SARS-CoV-2 pseudovirus.

Objective To systematically analyze the framework and core content of physical activity inclusive school health policies. Methods This study conducted systematic content analysis of key messages of WHO key documents related to physical activity and school health services, and constructed policy and research framework. WHO's key policy documents in the field of school health included: Making Every School a Health-Promoting School Implementation Guidelines, WHO Guidelines on School Health Services, and the Global Criteria and Indicators for Making Every School a Health-Promoting School, and the key documents in the field of physical activity mainly include Global Action Plan for Physical Activity Promotion 2018-2030: Strengthening Physical Activity for a Healthy World, and WHO Guidelines on Physical Activity and Sedentary Behavior (Children and adolescents). Results Physical activity, as a health strategy and development strategy, is one of the most important tools for achieving health-promoting schools. In the area of health and education, the key to building health-promoting schools is to focus on child functioning and development, with the goal of promoting healthy inclusion and equity in schools. In the school setting, physical activity for children and adolescents is integrated into the school health service continuum with a focus on health promotion. At the macro level, the state and relevant authorities should establish a strategic structure and strategic planning for the integration of physical activity into the school health service system. At the meso level, educational institutions should develop and improve school health service policies and programs, and improve school health service tools based on the requirements of WHO school health service guidelines. Child health services are achieved through the provision of high-quality physical education programs and after-school physical activities. At the micro level, guided by global standards for building health-promoting schools, physical activity is promoted in the form of lessons and activities for healthy child development. Integrating physical activity into the school health service system can be done in six areas: school health leadership and governance, school infrastructure funding, school health service delivery that supports physical activity, human resources for school health, school health-related medicine and technology, and school health information system. We need to implement health-promoting school policies, strengthen multi-level school leadership and governance, raise the necessary funds to develop human resources adapted to the construction of health-promoting schools and build programs to support physical activity. Conclusion School health service is an important area for promoting children's health and achieving the UN 2030 Sustainable Development Goals, and physical activity is an important strategy of school health services. Policy documents issued by WHO construct the integration of physical activity into the policy framework of the school health service system, of which the core component is to integrate physical activity into the health-promoting school with educational and physical activity approaches. According to the WHO six building blocks of health service system, the integration of physical activity into the school health requires strengthening school health leadership and governance, improving school infrastructure financing, developing school health human resources, developing school-based health-related medical technologies, and establishing a health information system for sharing student health data.

Objective To explore the theories, content and approaches of integrating physical activity in children's eye health service system in the context of health services. Methods From the perspectives of six building blocks of WHO health system, namely, leadership and governance, financing, human resources for health, service delivery, medical technology, and health information system, we analyzed the policy framework and key contents related to school-based eye health and physical activity, and explored how to promote the implementation of physical activity into the school-based eye health service system, and the integration of physical activity into the eye health continuum: prevention, intervention, rehabilitation, and health promotion. Results In perspective of health system, the integration of physical activity into school-based eye health services should be in accordance with the five principles of cross-cutting health services, namely, universal accessibility and equity, human rights, evidence-based, life-span, and empowerment. According to the World Vision Report, WHO advocates to build a person-centered eye health service system, and person-centeredness is the core concept of the new model of school-based eye health services and physical activity integration. WHO advocates a school-based approach to education and physical activity in health-promoting schools to promote student health, physical activity as a preventive, interventional, rehabilitation and health promotive measure related to children's eye health, and vigorously train professionals within schools who have knowledge and skills related to physical activity and eye health, build an information system on physical activity and children's eye health, and promote the integration of physical activity into the school-based eye health service system. Conclusion Physical activity is an important measure to promote children's eye health and an important component to achieve a person-centered eye health service system. Based on the six building blocks of the WHO health service system, a school-based eye health service that integrates a theoretical and methodological system of physical activity is constructed, requiring the provision of health promotion methods such as education and physical activity in the school setting, to enhance leadership and governance of eye health services based on educational and physical activity approaches in the school setting, establish new funding mechanisms, provide financial security, develop human resources related to physical activity for eye health, improve related service delivery systems, develop high-quality physical activity intervention eye health techniques and equipment, and integrate information on children's physical activity and eye health into school health information systems to achieve children's eye health and promote their physical and mental development.

Objective To study and analyze the theory, policy framework, and core content of physical activity policies and physical activity guidelines. Methods Using a policy research and content analysis approach and the theory of the six components of World Health Organization (WHO) health service system, we specifically analyze the theory, framework, and core content of WHO Global Action Plan on Physical Activity and WHO Physical Activity Guidelines. Results The Global Plan of Action for Physical Activity 2018-2030 (Action Plan) is an international policy document on physical activity issued by WHO that incorporates physical activity within the context of the seven principles of human rights, the life span, evidence-based practice, proportional universality, policy coherence and integration of health into all policies, participation and empowerment, and multisectoral partnerships into health services and social development. The Action Plan consists of four strategic objectives and 20 policy actions, covering six areas of WHO health service system, and the integration of physical activity policies into health services is of great importance in promoting the achievement of the United Nations Sustainable Development Goal 3 of universal health coverage. As a technical document for the implementation of the Action Plan, 2020 WHO Guidelines on Physical Activity and Sedentary Behavior (Guidelines) adopted the PI/ECO approach to analyze the physical activity needs of various groups of people, and provide guidelines to increase physical activity and reduce sedentary behavior for children and adolescents, adults, older adults, pregnant and postpartum women, people with chronic diseases and people with disabilities. The guidelines cover duration, frequency, and intensity of physical activity, types of physical activity, critical and important health outcomes of physical activity, and health risk prevention and related considerations. The Guidelines implement the relevant guiding principles of the Action Plan and aim to improve overall population participation in physical activity at the micro level and improve critical and important health outcomes for the overall population. Conclusion As a health and development strategy, the Action Plan promotes the integration of physical activity into the health delivery system to facilitate the achievement of the United Nations 2030 Sustainable Development Goal 3 of universal health coverage.The four strategic objectives and 20 policy actions of the Action Plan can be integrated into these six areas based on the six components of WHO Health Service Delivery System: leadership and governance, financing, human resources, service delivery, medical technology, and health information. As a technical document to implement the Action Plan, the Guidelines are based on the PI/ECO approach framework and provide guidance on increasing physical activity and reducing sedentary behavior for children and adolescents, adults, older adults, pregnant and postpartum women, chronic patients, and persons with disabilities. The core content addresses the target populations, duration, frequency, and intensity of physical activity, types of physical activity, critical and important health outcomes of physical activity, and health risk prevention and related considerations.

BACKGROUND: Albuvirtide is a once-weekly injectable human immunodeficiency virus (HIV)-1 fusion inhibitor. We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs. METHODS: We carried out a 48-week, randomized, controlled, open-label non-inferiority trial at 12 sites in China. Adults on the World Health Organization (WHO)-recommended first-line treatment for >6 months with a plasma viral load >1000 copies/mL were enrolled and randomly assigned (1:1) to receive albuvirtide (once weekly) plus ritonavir-boosted lopinavir (ABT group) or the WHO-recommended second-line treatment (NRTI group). The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks. Non-inferiority was prespecified with a margin of 12%. RESULTS: At the time of analysis, week 24 data were available for 83 and 92 patients, and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups, respectively. At 48 weeks, 80.4% of patients in the ABT group and 66.0% of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL, meeting the criteria for non-inferiority. For the per-protocol population, the superiority of albuvirtide over NRTI was demonstrated. The frequency of grade 3 to 4 adverse events was similar in the two groups; the most common adverse events were diarrhea, upper respiratory tract infections, and grade 3 to 4 increases in triglyceride concentration. Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group. CONCLUSIONS: The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug. This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.

BACKGROUNDPatients on hemodialysis have a high-mortality risk. This study analyzed factors associated with death in patients on maintenance hemodialysis (MHD). While some studies used baseline data of MHD patients, this study used the most recent data obtained from patients just prior to either a primary endpoint or the end of the study period to find the characteristics of patients preceding death.

METHODSParticipants were selected from 16 blood purification centers in China from January 2012 to December 2014. Patients' data were collected retrospectively. Based on survival status, the participants were divided into two groups: survival group and the death group. Logistic regression analysis was performed to determine factors associated with all-cause mortality.

RESULTSIn total, 4104 patients (57.58% male, median age 59 years) were included. Compared with the survival group, the death group had more men and more patients with diabetic nephropathy (DN) and hypertensive nephropathy. The patients preceding death also had lower levels of diastolic blood pressure, hemoglobin, serum albumin, serum calcium, serum phosphate, Kt/V, and higher age. Multivariate analysis revealed that male sex (odd ratio [OR]: 1.437, 95% confidence interval [CI]: 1.094-1.886), age (OR: 1.046, 95% CI: 1.036-1.057), and presence of DN (OR: 1.837, 95% CI: 1.322-2.552) were the risk factors associated with mortality. High serum calcium (OR: 0.585, 95% CI: 0.346-0.989), hemoglobin (OR: 0.974, 95% CI: 0.967-0.981), albumin (OR: 0.939, 95% CI: 0.915-0.963) levels, and dialysis with noncuffed catheter (OR: 0.165, 95% CI: 0.070-0.386) were protective factors based on a multivariate analysis.

CONCLUSIONSHemodialysis patients preceding death had lower hemoglobin, albumin, and serum calcium levels. Multivariate analysis showed that male sex, age, DN, low hemoglobin, low albumin, and low serum calcium were associated with death in hemodialysis patients.
